FIREPLACE.

Application filed July 15, 1926. Serial No. 122,617.

cause a circulation of air into the room be-' ing warmed and a portion of the air thus warmed is employed to obtain the complete combustion above referred to. f

The third object is so construct the lireplace that it can readily be installed within the ordinary fireplace or placed Vagainst a plain ywall and connected with the ordinary round smoke-flue opening such as are used,

with stoves and ranges.

The fourth object is to overcome one of the main objections to ordinary fireplaces namely the uneven heating of a room by causing it to circulate the air and maintain an even temperature at all points of the room under all ordinary conditions.

These, and other objects, will become more apparent from the specification following as illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of the fireplace. showing one half broken away in Vertical section along the line 1 1 in Figure 2. Figure 2 is a broken horizontal plan taken along the line 2 2 in Figurel. Figure 3 is a vertical transverse section taken along the line 3--3 in Figure' 1. Figure 4 is an enlarged detail of the firewall structure showing the air inlet openings between the imitation bricks. Figure 5 is a perspective View of the grate and ashflue door and damper with the operating mechanism. Figure 6 is a perspective view of a modified form of fireplace adapted to be set into the ordinary fireplace opening.

Similar numbers of reference refer to the same parts throughout the several views.

Referring in detail to the drawings, the form illustrated in Figures 1 to 3 inclusive is adapted to be placed against a plain wall 10 in which is a. chimney 11 such as are in common use.

' The fireplace itself has a base 12 in which to heatis mounted the grate 13, on its trunnions14.y

A pushrod 15 is attached to the arm 16 and is used to rock the grate 13. .Under the grate 13 is anash chute 17 having a trap door 18, mounted on the pivots 19 and connected by the link 2() to the arm 16 ofthe grate 13, so that when the grate 13v is in its closed position, the trap door will bel shut. Any rocking motion imparted to the grate 13 by the. rod 15 will also` rockthe' door 18 and allow the ashes to escape into the chute 17. Y

'A damper 21 is placed on the chute 17 Linder the front of the grate 13. A pushrod 22 is employed to operate the damper 21. Air inlet openings 23 are formed on the Linder sideof t-he base 12 through which air isdrawn from thefloor 24. A cover 2 is provided for the base 12. A curved guard 26 on the cover 25 prevents coals from getting out of the fireplace into the room. The i fire wall 27 resembles brickwork but is made of metal. The open joints 29 between the steps or bricks are chamfered to facilitate molding.

Behind the wall 27 and spaced therefrom is a back '30 preferably lined with insulating material 30-A, and spaced from the wall 10 if` desired; Side walls 31 are integral with the front 32` in the upper portion of which are formed the air outlet openings 33.

The outer edge 34 of the member 27is downturned to assist in controlling the paths of the air and gas currents. The member 27 is provided with a flange 35 by means of which it rjoins the front 32.

In some cases a grille 36 is hinged or otherwise attached to the edge 34 and is lined with metal cloth as a protection against sparks.

At the top of the firewall 27 is attached the smoke duct 37 which is provided with a damper 38 and its flange 39 connects with the smoke flue 11. A chain 40 is employed to operate the damper 38. Any type of mantle 41l may be used.

ln'the modification shown in Figure 6 there is illustrated the ordinary fireplace front 42 whose throat 43 is closed lwith a plate 44 adapted to receive the round smoke flue 45 of my fireplace. In this case the back 3() and side walls 31 are not required and the front 46 engages the front of the bricks 42. The other elements are the same as in the first described form ofthe device.

grate 13 with the dampers 2l and 38 open wWhen/the Walls become heated, the dampers are gradually closed andfheatedfair is sup-= plied to the combustion through the open-- ings29.

Only asinueh air is drawn thrcmghy the openings 2S) as isactually required bythe combustion. The' reinainde-rof theA air pass ingupwardly throu,3 the room through the openings 33.'

' It can he seen-that'by this construction the usual large labor item in i'repl'aoe construction isgreatly reduced and fireplaces lhaving undersized lues andi wrongly cone structed I'throatscaniiloeinadeL to operate inY aI more eiicient manner. No attemptlisgma-de at showing decorative elements since they do not enter into this invention.-

I claim:

l. A iireplfaee having ahfinged gra-te,v a grate-:holding yhase includingl a -firex` -Walh anl ashductfunder said grate havinga normally `link-*in a manner to open said door when wh the air spaceentersA .closed door-A thereon, a' link' connecting said grate "and door; and means'ifo'r aetuating said saidg-rate is opened.

A fireplace having a hinged grate, a girataholding base including a lire wall, an ash duct under said grate having a normally closed door thereon; a link connecting said grate and door, means for actuating said link in manner to open saiddoor Whensaid irate is openedg-an'da; damper for: controlling the supply ofai-rto the'under side 'of said A grate'.

3. A lilreplaee having, in combination, a hinged grate, a grate supporting base, an ash duct positioned under said gi'aute,` an asli duct door lon'said duct, a linlchetween said grateanddoor whereby said' ductfdoorfwilfl` be operated in unison with said grate-1n^e`ans for actuating said'grate and'doorconsis'ting" of a rod attached to said link, -a vlirevv Wall aroundl saidr grate, and outer Walls' enclos: ing said lire Wallis having openings therein; whereupon heated air may escape/'from the outer Walls into the room.
